Exploring the Volume of Cylinders

In this video, Mizzou Carter teaches how to find the volume of a cylinder. The lesson begins with an introduction to the concept of volume and the derivation of the formula for the volume of a cylinder, which is πr²h. Two worked examples are provided: the first uses a given radius and height, while the second uses a given diameter and height. The video emphasizes the importance of using the correct value for π as specified in the problem instructions.

What shape is the base of a cylinder?

• Circle

• Rectangle

• Triangle

• Square

What is the formula to calculate the area of a circle?

• PI * r^2

• 2 * PI * r

• PI * d

• 2 * r^2

How do you find the volume of a cylinder?

• Base area * Width

• PI * r^2 * Height

• PI * d^2 * Height

• 2 * PI * r * Height

What is the first step in finding the volume of a cylinder?

• Calculate the base area

• Find the diameter

• Multiply by PI

• Calculate the height

What value of PI is used in the lesson?
